Hot metal zinc can be applied after blasting and prior to painting. This is the process in which coils of zinc wire are fed through a tungsten steel spray gun, fuelled by oxygen and propane which is ignited and then burns the zinc onto the blasted surface. The zinc comes out in spray form hence creating the same effect as galvanising. Once applied, directly after blasting, the zinc layer can be left uncoated until the vessel goes onto the slip-way. There is no chance of rust developing before paint is applied.
